Increasing energy efficiency by tailoring the electric pulse pattern during Spark Plasma Sintering

Popis výsledku v původním jazyce

Studies on Pulsed Direct Current (pulsed DC), which is specially applied in Spark Plasma Sintering (SPS), has attracted much attention. The effect of the various pulse patterns on recorded currents, energy efficiency and mechanical pulsing are investigated by the constant input heating of SPS and a stable punch system. The results show that the recorded current increases while the energy efficiency decreases with the increasing ON/OFF ratio. The TiO2 powder was sintered by pulse patterns 12:2 and 10:9 with constant power input. An increase of one order of magnitude in grain size and 8% in density is shown after application of the pulse pattern 10:9, while the amount of consumed energy remained constant. When heated with different pulse patterns, the variation of the effective power and contact resistance induced by the mechanical pulse are two main reasons accounting for the varying energy efficiency. This unique SPS behavior was demonstrated by experiments and calculations.
